Keith graduated from Kewanee High School in 1966 and later attended Black Hawk College–East Campus. He served his country in the United States Navy as a member of the Naval Construction Battalions, better known as the Navy Seabees. A decorated combat veteran, he received a Presidential Unit Citation from President Lyndon B. Johnson for extraordinary heroism in action against the North Vietnamese Army forces during the Battle of Khe Sanh in the Republic of Vietnam.

Keith was employed for 22 years, retiring as a lieutenant with the Illinois Department of Corrections in 2001.

He had a great sense of humor and loved making everyone laugh. He enjoyed the outdoors, whether ranching with Toys the cow, Billy the goat and Spunky the mule, traveling in his motorhome, riding motorcycles, or watching his grandchildren’s sporting events. Above all, Keith loved his family and cherished every moment spent with them.
